Optical Line Monitoring
Broadband Access FTTx / Optical Line Monitoring / Optical Line Monitoring PDF
Overview
ftth Central office operates a lot of optical fibers both network side and client side when FTTx solution for broadband, more and more required as optical fiber line management. General optical line monitor solution is using as OTDR, the detached the service port and connected OTDR tester, therefore the in-service optical line management is very hard.
DASAN's Optical Line Monitoring system consist as 1xN OSW(Optical Switch) and WDM filter from OTDR signal TDM based gathering information, for online optical fiber cable monitoring equipment, high integration, complete function with 1U to 3U height. Depends on the monitoring port number, config as 8 ports to 32 ports in one box.
DASAN OLM supports as OTDR integrated(option) and out-of band OTDR also possible. DASAN OLM provides 2 PSU (Power Supply Unit) slots and hot-Swapping on the transponder module and easy managing by CLI display.
